When the new Rosslyn Metro entrance opened earlier this week, it became the first in what will be an exciting string of big transit projects opening in the DC region. Still to come: Metro, MARC, streetcars, and BRT.

The next big event will be on December 7, when MARC trains begin running on weekends between DC and Baltimore. MARC’s transition from a commuter railroad to a more general-purpose transit system will open up Baltimore and other parts of Maryland like never before.

After that come streetcars. Sometime in late December, or possibly January, DDOT expects to start running streetcars along H Street. Then in February, the Silver Line will open, and begin carrying passengers to Tysons Corner and Wiehle Avenue.

Finally, sometime in the spring of 2014 Alexandria will open its Route 1 transitway, marking the beginning of the first bona fide bus rapid transit line in the region. All together, it’s the most exciting time for transit openings in the DC area since the early 1980s, when Metrorail was opening new segments every few months.
